FIELD OF THE INVENTION

The present disclosure relates to a material tracking system. More particularly, the disclosure relates to tracking material stored on and drawn from a reel.

BACKGROUND

Many materials used in construction or the fabrication of products (e.g., wire, cable, tubing, yarn, rope, etc.) are sold from the manufacturer on reels. Distributing materials on reels allows users (e.g., installers, contractors, manufacturers, etc.) to easily obtain a desired amount of the material for a job or task and enables easier storage and materials control. A single reel of material is often used for multiple jobs. Many users manually track the usage of material from a reel while completing jobs. Some types of materials include a visual legend that is printed on the material at given intervals. Tracking the usage of material on reels is often necessary for inventory management, billing and project planning. Manually tracking the usage of material from a reel requires a significant amount of time and expense and necessitates a system for recording material use. In addition, manual tracking is subject to significant inaccuracies caused by human error. These inaccuracies contribute to waste and increase project cost.

A variety of material tracking systems have been previously developed for materials that are distributed from a reel. Some are generally of the type that attaches directly to the material, independent of the reel and tracks the movement of the line as it feeds from its container. Taymer International, Inc. (Markham, Ontario, CA) is one example of a distributer of measuring devices that are directly attached to the material being distributed. These devices are typically only used in the manufacture of cable because they use a system of complex rollers to measure the material as it is spooled out, which makes this solution expensive and prone to potential errors. This technical approach also requires recalibration of the devices for different material diameter.

Other material tracking systems are used in reel to reel audio tape monitoring, as exemplified in U.S. Pat. No. 5,808,824 to Kaniwa, et al. These systems combine reel to reel tape speed measurements with winding radius calculations to control tape feed through a complex series of measuring devices that are integrated with the machine that reads the tape. The system requires complex sensors on both reels along with calculations that feed back into the controlling device and require complex manufacturing and assembly. They are permanent components of the machinery and are not used to track inventory. In this system, the device uses a ratio between the tension of the tape and the torque output of the reel motors to calculate the radius of an empty take-up spool and then ultimately by tracking the tape fed calculations may be made to ultimately determine the radius of the working radius of the supply spool and the length of the fed tape.

Measurement of wire bonding loops is done in semiconductor fabrication as electronic wire is attached to various components as exemplified in U.S. Pat. No. 8,301,841 to Qin. These systems simply calibrate wire payout based on the timing of a payout mechanism and are not used to measure remaining length. They do not measure rotational variables from a spool, reel or other wire container.

U.S. Pat. No. 6,921,044 to Graber et al shows a device for storing and detecting the end of a wire as it is unspooled. The device uses the few wraps of wire closest to the drum to block the magnetic lines of flux from reaching the magnetic sensor mounted outside of the spool. As the last few wraps of wire no longer block the magnetic flux the sensor will momentarily pick up that flux once per rotation. If the sensor is hooked to an output source (e.g. Light, siren etc.) the output source will energize once per rotation informing the user that the wire is about to run out. Among other potential shortcomings, this device does not provide any advanced warning that the wire will be running out, let alone, provide any inventory management capabilities.

In the fishing gear industry, attempts have been made to develop sensor-based systems to track the amount of fishing line let out from a fishing reel. For example, U.S. Pat. No. 4,790,492 to Takashi provides for magnet-based sensor system for measuring and providing the length of fishing line paid out or reeled in. This unitary system teaches one-to-one correspondence between sensor sub-system, processor, and display. As such, among other potential shortcomings, the approach disclosed by the '492 Takashi patent is too expensive for use in simultaneously tracking multiple reels of material.

Therefore, a need exists to solve the deficiencies present in the prior art. What is needed is a system for tracking the remaining length of a material wound on a reel. What is needed is a system with a detection component to track and relay the length of material on a reel or spool. What is needed is a tracking system to accurately determine material paid out from a reel. What is needed is a system to aid in selection of a reel for a deployment job. What is needed is a system to centralize information relating to material on various reels. What is needed is a method of tracking material stored on and paid out from one or more reel. What is needed is a method of sensing use characteristics of a reel of material.

It should also be noted that various hardware and software-based devices, as well as various structural components may be utilized to implement the invention. Furthermore, and as described in subsequent paragraphs, the specific configurations illustrated in the drawings are provided as examples and embodiments of the invention. Alternative configurations are possible.

Referring now to FIGS. 1-16 , the material tracking system will now be discussed in more detail. The material tracking system may include a material, reel, detection element, digital logic components, battery and power components, transceiver and communication components, location receiver, enclosure, analytic components including one or more processor, interface component, and additional components that will be discussed in greater detail below. The material tracking system may operate one or more of these components interactively with other components to track material stored on and drawn from a reel.

An invention enabled by this disclosure relates to tracking the usage of materials from a reel using a material tracking system. FIG. 1 demonstrates a basic configuration of a material tracking system enabled by this disclosure. The system may include, among other components, a first processor 10 that may contain an input/output (I/O) unit 12, a memory 14 (which may be integral to the first processor 10), and a processing unit (CPU) 16, at least one sensor 18, optionally a detection element 20, one or more power supply modules (e.g. a coin-type or LiPo battery cells) 22, one or more indicators 26, and one or more communications modules, including a first transceiver 28. The indicators 26 may, for example, include one of more LEDs and/or a liquid crystal display (“LCD”). In one implementation, the controller 10 may be associated with a single printed circuit board (“PCB”) that is populated with one or more of electrical and electronic components that provide power, operational control, and protection to the material tracking system. The memory 14 may include, for example, a read-only memory (“ROM”), a random-access memory (“RAM”), an electrically erasable programmable read-only memory (“EEPROM”), or other flash memory. Memory 14 may store information regarding the rotation of the reel. For example, the memory 14 may contain the total number of forward rotations of the reel. In an embodiment including a real-time clock and/or a location receiver, for example a GPS receiver, the memory may also save time/date and/or locations in association with the reel rotational data. Finally, the memory may also store an identification number that is unique to the reel/material to allow a business to track the material remaining on one or more of reels substantially simultaneously.

The controller or first processor 10 may be operably connected via first transceiver 28 to an external device (e.g., a computer, a smart phone, a tablet), which may include a processing unit 16 and user interface 24 (i.e. combinations of software and hardware that are operable to, among other things, calculate the amount of material currently on a reel and activate the one or more indicators 26 or communicate with the one or more external devices). The processing unit 16 may be connected to a memory on the external device and may execute software that is capable of being stored in the RAM (e.g., during execution), the ROM (e.g., on a generally permanent basis), or another non-transitory computer readable medium such as another memory or a disc.

Software included in some embodiments of the material tracking system may be stored in the memory operably associated with the processing unit. The software may include, for example, firmware, one or more applications, program data, one or more program modules, and other executable instructions. The processing unit may be configured to retrieve from memory and execute instructions related to the control processes and methods described below, including for example, the instructions for performing calculations necessary to determine the current amount of material on the reel 30 (see FIG. 2 ).

The PCB may also include, among other components, one or more of additional passive and active components such as resistors, capacitors, inductors, integrated circuits, and amplifiers. These components may be arranged and connected to provide one or more of electrical functions to the PCB including, among other things, filtering, signal conditioning, or voltage regulation. For descriptive purposes, the PCB and the electrical components populated on the PCB are collectively referred to as the battery-powered measurement sub-system 100 (which may also be known as the counting chip). Furthermore, in some embodiments, the PCB includes means for affixing the sub-system 100 to a reel or a reel box. The means for affixing the system can be permanent or removable. In some embodiments, the PCB includes a cover or housing which is affixed to the PCB. The cover or housing can be permanent or, more preferably, removable. Where the reel or reel box is exposed to the elements, the housing can be waterproof or can contain a gasket or seal to prevent water, dust or other contaminants from reaching the PCB circuitry.

The user interface 24 may be included to control the material tracking system. The user interface may be operably coupled to the first processor 10 to receive or input, for example, physical parameters of a given reel 30 and/or the material stored on the reel for use in tracking usage of the material. Although shown as being associated with a smartphone that uses soft keys, the user interface 24 may include any combination of digital and analog input devices required to achieve a desired level of control for the system. For example, the user interface 24 can be comprised of a computer having a display and input devices, a touch-screen display, one or more of knobs, dials, switches, buttons, faders, and/or the like.

The power supply module 22 may supply nominal voltages to the material tracking system. The power supply module 22 may include one or more batteries or battery packs, and more preferably by one or more rechargeable batteries or battery packs. The power supply modules 22 may also be configured to supply lower voltages to operate circuits and components within the material tracking system.

The communication module 28 may send and/or receive signals to and/or from one or more separate communication modules. Signals may include, among other components, information, data, serial data, and data packets. The communication module 28 may be coupled to one or more separate communication modules via wires, fiber, and/or wirelessly. Communication via wires and/or fiber can be virtually any appropriate network topology known to those skilled in the art, such as Ethernet. Wireless communication can be any appropriate wireless network topology known to those skilled in the art, such as Wi-Fi, Bluetooth, Zig-Bee, etc.

In some embodiments, the communications module 28 is configured to receive an input. The input is, for example, a streaming input of data values, a data packet, a set of data, etc. The input includes, among other information, an input identifier (e.g., identification number) for a reel, one or more of physical parameters for a reel (e.g., reel width, reel core volume, etc.), an input identifier (e.g., identification number) for a type of material, data from a sensor 20, and one or more of physical parameters for a type of material (e.g., material length, material outer diameter, etc.). After the input has been received, the input may be transmitted or transferred to the processing unit 16. In another embodiment, at least some processing may be done locally on a processor locally and operatively connected to the sensor, without limitation. In some embodiments, the processing unit is configured to retrieve, from the memory, one or more of parameters for a type of material based at least in part on a received input identifier for a type of material. In other embodiments, the processing unit is configured to retrieve, from memory, one or more of parameters for a reel based at least in part on a received input identifier for a reel.

Now turning to FIG. 2 , which shows a common configuration of a reel 30, according to an embodiment of this disclosure. In this embodiment, the end cap 34 can be removable or integrated permanently into the reel 30. The detection element 20 may be coupled to the reel 30 and can be removable or permanently attached. In some embodiments, the detection element 20 is coupled to the outer edge of one of the flanges 38 of the reel 30. The battery-powered measurement sub-system 100 containing first processor 10 and sensors 18 are attached to the end cap 34 and is placed in such a position to track the rotation of the detection element 20.

In FIG. 3 , a close-up view of a flange 38 of a reel 30 is shown. A detection element 20 is shown attached to the outer edge of the flange 38.

When material is removed from or added to the reel, the reel rotates, which causes the detection element 20 to rotate. In this embodiment, the sensor 18 may transmit a signal each time it detects the proximity of the detection element 20 (e.g., every time the detection element 20 passes the sensor 18). In some embodiments, the signals indicate the current direction of rotation of the reel (e.g. clockwise, counter-clockwise). In one embodiment, sensors 18 are magnetic sensors. In alternate embodiments, sensor 18 may be a different type of sensor including, for example, a capacitive sensor, a laser sensor, an optical sensor, an infrared sensor, a touch sensor, accelerometers, etc. In some embodiments, the material tracking system includes one or more of sensors that are spaced apart. Each sensor 18 in the one or more sensors may transmit a signal when the detection element passes. In one embodiment, the detection element 20 may be a type of magnet (e.g., neodymium). In alternate embodiments, the detection element 20 is any type of element appropriate for the type of sensor used in the system.

The first processor 10 may be configured to receive signals from the sensor(s) 18. Upon receiving the signals, the controller 10 may determine whether the reel 30 has rotated in a first direction (e.g., clockwise) or in a second direction (e.g., counter-clockwise). In some embodiments, the first processor/controller 10 may receive a separate signal from each sensor 18 in one or more of sensors and determine the rotation direction of the reel 30 based on the order in which the signals are received. For example, the controller 10 may determine that the reel 30 is rotating in a first direction when a signal from a first sensor 18 a is received before a signal from a second sensor 18 b, and the controller may determine that the reel 30 is rotating in a second direction when the signal from the second sensor 18 b is received before the signal from the first sensor 18 a.

The processing unit 16 may be configured to determine a new or updated value for the amount (e.g., length) of material on the reel 30. In some embodiments, the controller 10 may determine the new amount of material on the reel 30 using the following equations:

$\begin{matrix} {{x_{New} = {x_{CURRENT} - {2\pi\sqrt{\frac{\left( {\left( {{L*\pi*\left( \frac{d}{2} \right)^{2}} + n} \right)/w} \right)}{\pi}}}}},} & {{Equation}\mspace{14mu} 1} \\ {x_{New} = {x_{CURRENT} + {2\pi{\sqrt{\frac{\left( {\left( {{L*\pi*\left( \frac{d}{2} \right)^{2}} + n} \right)/w} \right)}{\pi}}.}}}} & {{Equation}\mspace{14mu} 2} \end{matrix}$

Wherein:

L=starting length of the material on the reel in inches

d=diameter of the material on the reel in inches

n=volume of the core of the reel in cubic inches

w=width of the reel (i.e., distance between the flanges) in inches

xCURRENT=the current value for the length of the material on the reel in inches, and

xNEW=the new value for the length of the material on the reel in inches

In this embodiment, the processing unit 16 may use equation 1 when the reel 30 has rotated in the first direction (i.e., material has been removed from the reel 30). The processing unit 16 uses equation 2 when the reel 30 has rotated in the second direction (i.e., material has been added to the reel 30). Use of inches as the unit of measurement in Equations 1 and 2 are provided for exemplary purposes and any commonly used length unit (e.g. feet, yards, meters, centimeters, etc.) or any fraction thereof can be used, without limitation. In some embodiments, the above-described parameters of the reel 30 and material are retrieved from the memory. In other embodiments, the above-described parameters of the reel 30 and material are received via the communication module 28.

After calculating a new or updated value for the amount of material on the reel 30, the processing unit may transmit an output. The output is, for example, a streaming output of data values, a data packet, a set of data, etc. The output can include, among other things, an identifier (e.g., identification number) of the reel 30, an identifier (e.g., identification number) of the material, and/or the current value for the amount of material on the reel 30. This value can be, for example, in any commonly used linear measurement with inches being one embodiment.

In some embodiments, the second side 80 of the second PCB includes, among other components, a first controller 10, a pair of sensors 18 and a connector 46. The connector 46 can be any type of standard connector for a PCB, including solid pads, holes or pins. In this embodiment, the connector 46 comprises one or more of holes, among other components. In one embodiment the PCB has a series of openings 72 to affix the PCB to an end cap. Standard affixing means such as screws or nails or the like can be used in the openings 72 to secure the PCB onto the end cap.

FIG. 10 shows an alternate embodiment of a first side 90 of a second PCB. This PCB may include, among other components, a user interface 24, an indicator 26, and a power supply module 22. In some embodiments, the user interface 24 is an LCD screen which displays a number that represents the current amount of material on the reel, in approximately real time. In some embodiments, the user interface 24 displays information about the nature of the material and the reel that has been input by a user from a mobile computing platform such as a smart phone, tablet, and/or computer. In some embodiments, the indicator 26 is an LED which activates or deactivates based on the amount of material on the reel. For example, the LED activates when less than 10% of the original amount of material is left on the reel. In some embodiments, the power supply module 22 holds a battery (not shown).

FIG. 11 shows an alternate embodiment of a second side 100 of the second PCB and includes, among other components, a second controller 10, a connector 46, and a communication module 28. In a preferred embodiment, the communication module 28 is wireless (e.g. Bluetooth, BTLE, Kirkland, Wash.). In some embodiments, the second PCB is coupled to a first PCB via the connector 46. In some embodiments, the second controller 10, among other operations, receives signals from the first controller of a first PCB, performs the material tracking operations described above, operates the user interface 24 and indicators 26, and transmits information to other components wirelessly via the communication module 28. In some embodiments, the second PCB is removably affixed to a reel box by a user after a reel is installed in the reel box. Means for affixing the second PCB can include any common means such as screws, nails, hook and loop connectors, wire, etc. In some embodiments, the second PCB is reusable and is used with multiple first PCBs.

As illustrated in FIG. 12 , in some embodiments, a second PCB 110 is coupled to a reel box 112 that contains, among other components, a reel (not shown). In some embodiments, the second PCB 110 is coupled to the reel or reel box 112 during packaging of the material on the reel. In a preferred embodiment, the second PCB is removable from the reel box 112 and is used with multiple first PCBs. In some embodiments, the second PCB is disposable. An opening 114 for the material to be removed from the reel 112 110 is shown. A slot 116 for the removable second PCB to be connected to the first PCB (not shown) for up- and down-loading of information is shown. The slot 116 is oriented with the reel box 112 so that the connectors of the first PCB and second PCB 110 may align.

By way of example, according to an embodiment enabled by this disclosure, a first PCB containing magnetic sensors is affixed at a distance of 6 inches from the central axis of a first end cap that is sized for a reel of wire (Cat 5 Plenum, Anixter, Glenview, Ill.). The first and second end cap are placed on the reel. A magnetic detection element (#8 Screw Neodymium magnet, Applied Magnets, Plano, Tex.) is attached to a flange of the reel opposite from the first end cap. The reel is placed in a reel box and shipped to a user. The user may program a second PCB with the input identifier by a laptop computer which sends the information wirelessly to the transceiver in the second PCB. The user then attaches the second PCB to the outside of the reel box. As the user retrieves wire from the reel box, the reel rotates and the sensors of the first PCB detect the rotation of the detection element. The sensors send a signal to the second PCB with the number of rotations which can be a whole number or a fractional number. The sensor also detects, tracks and transmits reverse rotations as wire is replaced or unused wire is rewound. The second PCB may be loaded with software which performs the calculations as described above using either Equation 1 for forward rotation (use of wire) or Equation 2 for reverse rotation (respooling or reloading). The second PCB may then send a signal containing the current amount of wire to the laptop computer for material tracking purposes.

In an alternate example, a first PCB containing optical sensors is affixed at a distance of 1 foot from the central axis of a first end cap that is sized for a reel of wire (18-02 OAS, Lake Cable 529 Thomas Drive Bensenville, Ill.). The first and second end cap are placed on the reel. An optical detection element (Light to digital converter, AMS, Styria Austria) is placed on a flange of the reel opposite from the first end cap. This is repeated for multiple reels of wire. The reels are shipped to a user. The user programs a second PCB with the input identifier of each reel with a smart phone. The smart phone sends the information to a wireless transceiver in the first PCB. As the user retrieves wire from the reel box, the reel rotates and the sensors of the first PCB detect the rotation of the detection element. The sensors send a signal to the smart phone with the input identifier and the number of rotations which can be a whole number or a fractional number. The sensor also detects, tracks, and transmits reverse rotations as wire is replaced or unused wire is rewound.

Now turning to FIGS. 13-14 , and additional embodiment will be described without limitation. FIGS. 13-14 show a common configuration of a reel 30 with one or more attached sensors 18, for example, attached to flanges 38. In this embodiment, an end cap can be removable or integrated permanently into the reel 30. The sensor 18 may include an accelerometer or other device capable of detecting an angular orientation. The sensor 18 may be operatively connected to a battery-powered sub-system 100, such as the version illustrated in FIG. 1 . In one example, the sensor 18 may be communicatively connected to the battery-powered sub-system 100 wirelessly, without limitation. Since the position of the reel may be determined from the angular orientation of the sensor, this embodiment may advantageously remove the need for separate detection elements 20 as described along with other embodiments.

Referring now to FIG. 13 , the reel 30 illustrates the sensor 18 installed to a reel flange 38. The sensor may indicate an angular orientation, which may represent a starting state for determination of a number of rotations of the reel 30. As the reel 30 is rotated, the sensor may be repositioned along the X and/or Y axis in respect to a Z axis about which the reel 30 may be rotated. In one embodiment, the sensor 18 may measure changes in angular orientation about a single X or Y axis. In another embodiment, the sensor 18 may measure changes in angular orientation about both the X and Y axis substantially simultaneously, which may provide a vector value. As the reel 30 is rotated, for example, as material included by the reel 30 is paid out, the location of the sensor 18 will change, which will change the angular orientation of the sensor 18 with respect to the rotational Z axis of the reel 30. For example, an initial location of the sensor 18 may be a location such as shown in FIG. 13 and the subsequent location of the sensor 18 may be a location such as shown in FIG. 14 .

The frequency at which the sensor 18 may determine angular orientation may be set for a given application, precision, and desired quantity of data produced. In one example, provided without limitation, an accelerometer included in a sensor 18 may determine angular orientation at a rate of 40 Hz. Sensor data may be included in local storage and may processed locally to determine rotations and total amounts paid out. This initial processing being performed locally may advantageously reduce the amount of data having to be transmitted from local memory to global memory. For example, local processing may reduce 40 Hz of sensed raw angular orientation data to 1 Hz of processed data indicative of material paid out, rotational direction, material remaining on the reel, and/or other information. This embodiment may additionally reduce the need for a large local memory, for example and without limitation, to quantities around 4 megabytes, advantageously reducing the cost of materials to produce a system enabled by this embodiment. Alternatively, the raw data read by the sensor 18 may be transmitted to global memory for remote processing and analytics.

Data may be communicated via a transceiver, for example, via WiFi, 4G, 5G, cellular data, or networking protocols that would be appreciated by those of skill in the art. In some embodiments, a gateway may be provided to bridge communication protocols between a global network, such as an intranet and/or internet, and a local wireless network between the gateway and the sensor 18.

In this embodiment, the sensor 18 may report its angular orientation for a given positional location, which may indicate a change from a previously reported angular orientation. The change in angular orientation may be analyzed to determine a rate of change, direction of change, number of rotations, and other information relating to the winding or paying out of material included by the reel 30. A location receiver may be included with the sensor to determine a geographic position of the reel 30 to assist with determining whether material is being paid out or whether the reel is simply being rolled for transportation or relocation. The location receiver may use GPS, cellular triangulation, MM waves, ultrawideband tracking, and other location determining techniques to determine a location of a spool or reel. The reading of values from the sensor 18 may additionally be selectable between on and off states manually and/or dynamically from an operator and/or controller.

By including an accelerometer in the sensor, this embodiment advantageously removes the need for additional sensors to be included in a box housing the reel. The sensor may include features to assist with identification, for example, RFID, near-field communication (NFC), Bluetooth, and/or other protocols that would be appreciated by those of skill in the art. For example, the unique identification number may be communicated via one or more of the above features to assist with identification of a reel. Wireless data may be transmitted from the device including the sensor via a transceiver and/or radio, which may include and/or interface with an antenna, for example, a PCB antenna, chip antenna, external antenna, and/or other antenna.

In an embodiment, a processing unit 16 on a smart phone (or other portable computing device) may be loaded with an application which performs the calculations as described above using Equation 1 for forward rotation (use of wire), or Equation 2 for reverse rotation (respooling or reloading), and/or another equation. The smart phone application may further provide a spreadsheet on the smart phone screen containing the current amount of wire for each reel by using the unique identification number stored in the memory associated with each reel. This information may then be uploaded at a preferred interval (e.g. per-second, per-minute, hourly, daily, weekly, monthly) to software on a desktop computer in the user's inventory control office.

The basic information regarding the amount of material, time/date, location, and/or other information obtained from the battery-powered measurement sub-system 100 may be manipulated by the processing unit 16 to determine a variety of potentially useful management metrics. For example, the data may easily be mathematically and logically organized and reorganized to determine: (a) the date and time of each pull; (b) location of each pull; (c) accurate billing based on time and materials actually expended at a specific job; (d) reducing overhead and minimizing wasted materials; and (e) maximize installer efficiency. Information may be sharable or saleable to distributors, manufacturers, and other parties to increase efficiencies and better anticipate market demands.

The processing of data may be adjusted to increase accuracy of the calculations, which may be performed locally and/or over a networked computing device. Feedback may be provided to the system regarding calculated payout rates, actual material paid out, margins of error, conditions of the payout, and other factors to improve the accuracy of the system. Calculations may be manipulated through the introduction and alteration of correction factors. For the purpose of this disclosure, a correction factor is intended to include constants, variables, scalar values, calibrations, formulae, and other mathematical operations to manipulate the calculations performed on sensed data to determine usable values and information. For example, a correction factor may be applied to account for the width of cable on a reel, whether the cable is a single conductor, tightness of spooling, respooled material, and other factors.

The feedback may be substantially automatically calculated through use of the system, manually entered, dynamically learned, and/or otherwise received. In one embodiment, a machine learning approach may be used to adjust correction factors based on iterations between multiple operations. For example, machine learning can be used to determine a proposed correction factor, check whether the correction factor improved accuracy of the calculation, and adjust the predictive weight of using the correction factor based on the results. The machine learning operation may be initially based on a rule set. This iterative process can be substantially continually repeated, allowing refinement of the calculation accuracy. The feedback may additionally be used with a fault tree, which may use data science to learn and improve initialization for various operating conditions. Sensors may be associated with information regarding material on a reel to further increase the likelihood of choosing proper correction factors and other variables associated with the material to improve accuracy.

In particular, the system allows an installer, his supervisor, supply ordering clerks to see the length wire remaining in each box on site and at the office. For an installer on-site, the information means substantially limiting wasted labor time guessing whether a spool will make it to the end of the run; or risking a time exhausting repull. On the other hand, a supervisor would be able to see how many feet of cable have been installed versus the amount of cable use projected for a given job.

In one embodiment, the interface and operations performed by the processor may be updatable. For example, electronic components relating to the sensor and sub-system may be updated via firmware flashing, register editing, configuration files, over-the-air updates, security updates, and other manipulation of data that could affect operation. The sensor and/or additional components may include one or more expansion ports, which may provide additional functionality through supplemental hardware. Solder contacts may additionally be provided for the installation of hardware, for example, a radio or antenna.

Scrapping cable is leakage that most utilities and installers just deal with right now because of the labor cost to sort it out. A tool and system enabled by this disclosure can advantageously and substantially seamlessly provide actionable inventory data that allows users to use a large portion of their cable efficiently. In view of the functionality of the present system, the remaining inventory after a job is complete may be put into ‘My Random Lengths Inventory’ these random lengths will be easily searchable for use at future job sites.

Additionally, reels may be selected such that an amount remaining after a job is a usable quantity that can be used on a future job. Trends may be determined to assist with efficiently ordering cable and wire quantities most likely to be use substantially completely. For example, historic data on how much cable was pulled at which location on which day may be used to assist in spotting trends related to issues with job types or indicate which installers are most efficient.

The enclosure will now be discussed in greater detail. In one embodiment, at least part of the sub-system 100 may be included in an enclosure. The enclosure may include seals, liners, and/or other features to minimize or prevent the introduction of moisture, dirt, and dust into an interior volume encompassed by the enclosure. The enclosure may be made of various materials, including plastics, metals, wood, and other materials that will be appreciated by skilled artisans. The enclosure may be configured such that it may be installed in a substantially flush orientation with the reel and/or reel flange. The enclosure may include an antenna operatively connectable to a radio or transceiver. The sensor may include an expansion port, which may be accessible by the enclosure.

More specifically, without limitation, the network communication device 1520 may communicate and relay information from one or more components of the illustrative computerized device 1500, or other devices and/or components connected to the computerized device 1500, to additional connected devices 1532, 1534, 1536, and/or 1538. Connected devices are intended to include, without limitation, data servers, additional computerized devices, mobile computing devices, smart phones, tablet computers, and other electronic devices that may communicate digitally with another device. In one example, the illustrative computerized device 1500 may be used as a server to analyze and communicate data between connected devices.

The illustrative computerized device 1500 may communicate with one or more connected devices via a communications network 1508. The computerized device 1500 may communicate over the network 1508 by using its network communication device 1520. More specifically, the network communication device 1520 of the computerized device 1500 may communicate with the network communication devices or network controllers of the connected devices. The network 1508 may be, for example, the internet. As another example, the network 1508 may be a WLAN. However, skilled artisans will appreciate additional networks to be included within the scope of this disclosure, such as intranets, local area networks, wide area networks, peer-to-peer networks, and various other network formats. Additionally, the illustrative computerized device 1500 and/or connected devices 1532, 1534, 1536, and/or 1538 may communicate over the network 1508 via a wired, wireless, or other connection, without limitation.

Memory 1512 may be used for storing programs and/or data during operation of the illustrative computerized device 1500. Thus, memory 1512 may be a relatively high performance, volatile, random access memory such as a dynamic random-access memory (DRAM) or static memory (SRAM). However, memory 1512 may include any device for storing data, such as a disk drive or other non-volatile storage device. Various embodiments in accord with the present disclosure can organize memory 1512 into particularized and, in some cases, unique structures to perform the aspects and functions of this disclosure.

Components of illustrative computerized device 1500 may be coupled by an interconnection element such as bus 1514. Bus 1514 may include one or more physical busses (for example, busses between components that are integrated within a same machine) but may include any communication coupling between system elements including specialized or standard computing bus technologies such as USB, Thunderbolt, SATA, FireWire, IDE, SCSI, PCI and InfiniBand.

The instructions may be persistently stored as encoded bits or signals, and the instructions may cause a processor to perform any of the functions described by the encoded bits or signals. The medium may, for example, be optical disk, magnetic disk or flash memory, among others. In operation, processor 1510 or some other controller may cause data to be read from the nonvolatile recording medium into another memory, such as the memory 1512, that allows for faster access to the information by the processor than does the storage medium included in the storage system 1518. The memory may be located in storage system 1518 or in memory 1512.

Further, the disclosure is not limited to a particular memory system or storage system.

Although the above described illustrative computerized device is shown by way of example as one type of illustrative computerized device upon which various aspects and functions in accord with the present disclosure may be practiced, aspects of the disclosure are not limited to being implemented on the illustrative computerized device 1500 as shown in FIG. 15 . Various aspects and functions in accord with the present disclosure may be practiced on one or more computers having components than that shown in FIG. 15 . For instance, the illustrative computerized device 1500 may include specially-programmed, special-purpose hardware, such as for example, an application-specific integrated circuit (ASIC) tailored to perform a particular operation disclosed in this example. While another embodiment may perform essentially the same function using several general-purpose computing devices running Windows, Linux, Unix, Android, iOS, MAC OS X, or other operating systems on the aforementioned processors and/or specialized computing devices running proprietary hardware and operating systems.

The illustrative computerized device 1500 may include an operating system that manages at least a portion of the hardware elements included in illustrative computerized device 1500. A processor or controller, such as processor 1510, may execute an operating system which may be, among others, an operating system, one of the above-mentioned operating systems, one of many Linux-based operating system distributions, a UNIX operating system, or another operating system that would be apparent to skilled artisans. Many other operating systems may be used, and embodiments are not limited to any particular operating system.

The processor and operating system may work together define a computing platform for which application programs in high-level programming languages may be written. These component applications may be executable, intermediate (for example, C# or JAVA bytecode) or interpreted code which communicate over a communication network (for example, the Internet) using a communication protocol (for example, TCP/IP). Similarly, aspects in accord with the present disclosure may be implemented using an object-oriented programming language, such as JAVA, C, C++, C#, Python, PHP, Visual Basic .NET, JavaScript, Perl, Ruby, Delphi/Object Pascal, Visual Basic, Objective-C, Swift, MATLAB, PL/SQL, OpenEdge ABL, R, Fortran or other languages that would be apparent to skilled artisans. Other object-oriented programming languages may also be used. Alternatively, assembly, procedural, scripting, or logical programming languages may be used.

Additionally, various aspects and functions in accord with the present disclosure may be implemented in a non-programmed environment (for example, documents created in HTML5, HTML, XML, CSS, JavaScript, or other format that, when viewed in a window of a browser program, render aspects of a graphical-user interface or perform other functions). Further, various embodiments in accord with the present disclosure may be implemented as programmed or non-programmed elements, or any combination thereof. For example, a web page may be implemented using HTML while a data object called from within the web page may be written in C++. Thus, the disclosure is not limited to a specific programming language and any suitable programming language could also be used.

An illustrative computerized device included within an embodiment may perform functions outside the scope of the disclosure. For instance, aspects of the system may be implemented using an existing commercial product, such as, for example, Database Management Systems such as a SQL Server available from Microsoft of Redmond, Wash., Oracle Database or MySQL from Oracle of Redwood City, Calif., or integration software such as WebSphere middleware from IBM of Armonk, N.Y.

In operation, a method may be provided for tracking material stored on and drawn from a reel. Those of skill in the art will appreciate that the following methods are provided to illustrate an embodiment of the disclosure and should not be viewed as limiting the disclosure to only those methods or aspects. Skilled artisans will appreciate additional methods within the scope and spirit of the disclosure for performing the operations provided by the examples below after having the benefit of this disclosure. Such additional methods are intended to be included by this disclosure.

Referring now to flowchart 1600 of FIG. 16 , an illustrative method for an example operation of a material sensing operation will be described, without limitation. Starting with block 1602, the operation may begin by reading angular orientation values of a sensor including an accelerometer, which may include X and/or Y coordinates. (Block 1604). The angular orientation values may be compared with the last reading taken by the sensor. (Block 1606). It may then be determined at Block 1610 whether a significant change in readings is detected.

If a significant change in readings is not detected in the operation of Block 1610, the operation may proceed to store the current X and/or Y coordinates as the new last reading. (Block 1644). The operation may then sleep for a period. (Block 1646). The sleep period may be defined manually, adjusted dynamically, or be substantially automatically adjusted based on analyzing feedback. The operation may then return to Block 1064 and again read the values from the sensor.

If a significant change in readings is detected in the operation of Block 1610, the vector direction and amplitude may be determined using the X and/or Y coordinates. (Block 1612). The operation may then compare vectors stored in an array of multiple elements. (Block 1614). It may then be determined at Block 1620 whether enough vectors exist in the array to make a decision.

If insufficient vectors are determined to exist during the operation of Block 1620, the current vector may be stored in an array, such as a “first in, first out” (FIFO) array of multiple numbered elements. (Block 1642). The operation may then continue to Block 1644 to proceed as discussed above.

If sufficient vectors are determined to exist during the operation of Block 1620, it may then determine whether the reel is in a spinning or rolling state. (Block 1630). If it is determined at Block 1630 that the reel is in a rolling state, the operation may continue to Block 1642 to proceed as discussed above.

If it is determined at Block 1630 that the reel is spinning, the operation may calculate the change in angular orientation since the last X and/or Y reading. (Block 1652). An algorithm may then be used to calculate the length of material removed from the reel based on the change in angular orientation as the reel is spun. (Block 1654). The current reel length may then be stored to memory. (Block 1656). The operation may then continue to Block 1642 and proceed as discussed above.

While various aspects have been described in the above disclosure, the description of this disclosure is intended to illustrate and not limit the scope of the invention. The invention is defined by the scope of the appended claims and not the illustrations and examples provided in the above disclosure.
